A lot depends on the type of story you are trying to write.
If you want to have multiple view points of different characters or show what other characters are doing that cannot be seen by the main character then third person is the best perspective. You can write multiple characters in first person, but the risk of being boring and repetitive is quite high, and it can also be confusing if switching back and forth.
The only story I have written in first person is a fat girl fetish series called 'My Best Friend's Crazy Fat Sister'. The first person perspective worked well as it had a small cast of four main characters who each represent the four personality types - melancholic, sanguine, choleric and phlegmatic. I wrote from the perspective of the main male character who is the melancholic personality type, as a main part of the story is how he struggles with his bizarre fetishes over his friend's insane fat sister. There was no need to go inside the minds of the crazy fat girl (the sanguine character), her long suffering brother (the phlegmatic character) or the brother's short-tempered wife (the choleric character), so first person was the best choice here.
Contrast this with my story 'Bridget the Bossy Bridezilla', which is a series of interwoven stories that come together by one specific event at the end. Third person was the only practical perspective for this.
But whether you decide to your story works better in first or third person, second person perspective is best avoided.
